. To all whom it may concern:

Be it known that 1, JOHN M. CHRrsrorFEL,

a citizen of the United States, residing, at

Milwaukee, in the county of Milwaukee and State of Wisconsin, haveinvented; certain new and useful Improvements in Fluid- Motors; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same. 6

This invention relates particularly to fluid motors and has particularreference to new and useful improvements in that type of water wheelknown as bucket rotors.

, As its principal object .this invention aims to increase theefficiency of bucket water wheels by providing a simple and practicalmotor designed with such regard to'proportion, number and arrangement ofparts that the-waste of pressure and the power transmission is guardedagainst by successively impinging each unit of fluid volume against anumber of rotor buckets.

A still further object of this invention contemplates the provision of alight andeflicient fluid motor which may be readily attached to anystandard form of water spigot or hydrant.

The above andadditional objects are accomplished by such means as areillustrated in the accompanying drawings described in the followingspecification and then more particularly pointed out in the claims whichare appended hereto and form a part of this application.

With reference to the drawings, wherein I have illustrated the preferredembodiment of my invention as it is reduced to practice, and throu houtthe several views of which similar re erence numerals designatecorresponding parts: Figure 1 is a side elevation of the motorillustrated in assembled relation to a water faucet, parts of the casingbeing broken away to more clearly disclose the assembled relation of theinterior parts. Fig. 2 is an edge view of the rotor showing the bucketsin section. Fig. 3 is a modified form of the elements illustrated inFig. 2. Fig. 4 is a section on the line 44 ofFigpl.

Fig. 5 is an additional modified form of the features illustrated inFig. 2. Fig. 6 is a detail view in perspective of one of the bucketbaflie cores. Fig. 7 is a transverse sectional view taken on line 77 ofFig. 5. Fig. 8 is a detail. perspective of one of the buckets indissembled position.

Proceeding now to the description of the drawings, the preferred form ofmy invention includes a motor casing 1, provided with the customarytangential internal screw threaded attaching nipple 2, and an outletport 3. Keyed on a concentric shaft 4 jour naled at diametricallyopposed openings in v the walls of the casing 1 is the rotor of mylnvention which includes a rotor disk 5 on the periphery of which isformed a double tional diamond-shaped baffle core 9. The .bucket casings8 are preferably made of sheet metal of any suitable nature and areformed in the nature of cross-sectionally U-- shaped casings, the sidewalls 10 of the casing being directed inwardly and angularly at theirlower end, producing a substantially funnel-shapedescape port for eachbucket.

In mounting the bucket casings 8 on the flange 6 it has been founddesirable to pro vide the flange 6 with spaced grooves 7 disposed toreceive the curved edges 11 of the casing. Each of the buckets 8 arepreferably provided with centrally'located apertures 14, the use ofwhich will be more fully hereinafter described. The area of the surfaceof the bucket casings 8 immediatelyadas a supportvfor the core 9. Thebafiie core 9 is made preferably hollow, and it is important that saidcore be diamond-shaped in cross section as will be hereinafterdisclosed. The inner edges of the member 9 are curved to correspond withthe curvature of the flange 6. The battle core 9 is formed of a singlesheet of metal bent to form preferthan the casing. The inner edges 20 ofthe core are adaptedt'o conform to the curvature of the rotor 5. Inassembling the entire bucket. the member 9 is mounted in the desiredposition on the outer face of the flange 6 and the casing 8 is mountedwith its curved edges seated in'the grooves formed in the member 6,after which a bolt 12 provided with the customary head 13 is passedthrough a suitable apertured depression 14 formed in the front portionof the casing 8, the bolt being then directed through the member 9 andsubsequently screw threaded into a suitable bore tapped in the member 5,as illustrated at 15 in Fig. 1.

In the modification of the bucket structure illustrated in Figs 3 and 5,it willsbe ob-- served that the one point of diflerence in the formationof the buckets resides in the fact that the angular relation of theconverging portion of the walls 10 of the casing 8 and the angularrelation of the sides of the baffle cores 9 is varied for a purpose tobe hereinafter clearly disclosed.

. The actual structure of the 'motor being thus disclosed it now remainsto describe the operation of the device and to enumerate the peculiaradvantages resulting from the novel v bucket structure of thisinvention.

Briefly the operation is as follows: The water issuing from the nozzleof the faucet is ejected into the adjacent bucket striking the upperapex of the baffle 9, and the water being thus divided impinges firstupon the upper adjacent walls of the baflle and then on the convergingwalls 10 of the casing. It will thus be seen that in each bucket'thereare four oints of impingement for each unit of flu1d volume which isejected into the motor. The utilization of the fluid does not terminateat this point, however, for as the fluid strikes the converging walls ofthe casing of the first bucket it is directed'against the upperdiverging walls of the next adjacent diamond-shaped baffle, being thencedeflected to impinge against the converging walls 10 of the casing ofthe second bucket.

Each unit of water is thus subjected to contact with a number of buckets7, inasmuch-as the water will continue to act in rotatin the wheel 5 bypressure upon the buckets until'each volume unit has traveled through asmany buckets as are necessary to absorb all of the incoming fluid. Itwill also beobserved that this peculiar design of bucket provides aneffective means for absorbing and transformmg a maximum 'amount of waterpressure a thepressure 1n the nozzle is increased. This feature isbelieved to be an essential. one and as such it is desirable thatparticular emphasis be laid upon it.

From the foregoing disclosures it is apparent that this inventionrovides a simple yet eificlent fluid motor a ording maximum utilizationof each pressure unit of the incoming fluid by permitting the stream ofwater to play successively upon a number of buckets. a

*In reduction topractice, Ihave found that the form of my invention,illustrated in :the drawings and referred to in the abovedescrip'tion,'as the preferred embodiment, is the most eflicient andpractical; yet realizing that the conditions concurrent with theadoption of my device will necessarily vary, I desire to emphasizethe-fact that various minor changes in details of. construction,proportion and arrangement of parts may be resorted to, when required,without sacrificing any of the advantages of my invention, as defined inthe appended claims.
